A crime has two parts: the mental part (mens
rea) and the physical part (actus reus).Actus reus can be interpreted to include your conduct, the harm
that your conduct caused, plus the causal link between the conduct and the
harm.

Murder requires a physical result (a dead
person).Some crimes, however, dont
require a result immediately caused by your conduct (e.g. drunk driving).They may require something called social
harm, about which more later.
